We hold expertise in the production of premium quality Non Asbestos Brake Liner. These are developed using modern technology from the quality approved raw materials as per the specifications of our clients. Recognized for their high wear resistance, high co-efficient of friction and durable finish standards, they find applications in numerous industries.

Features:


  • Good thermal stability up to 450°C, for a short term up to 800°C
  • Small effect on the opposite surface
  • Suitable for grinding, drilling and recess work
  • Friction co-efficient stability in a wide range of operating conditions

    Recommended operating conditions:


    • Specific pressure: p < 3.5 MPa
    • Sliding speed: v < 40 m.g-1
    • Temperature sustained: 450°C
    • Short term temperature: 800°C
    • Friction surface: Steel, cast iron, cast steel

      Friction data:


      • Dynamic coefficient of friction fdyn: 0.350 – 0.550
      • Static coefficient of friction fstat: 0.450 – 0.530

      Physical – Mechanical characteristics:


      • Density: γ = 4.6 g/cm3 • Specific heat : c = 5.1kJ/kg.K
      • Coefficient of thermal conductivity: λ = 4.0 W/m.K
      • Coefficient of thermal expansion: α* = 17.6 x 10-6/K
      • Modulus of elasticity: Ep = 393 MPa (under compression.)
      • Tensile strength: δdt = 26 MPa
      • Shearing strength: δds = 53 MPa*α(20-500°C)

        Friction characteristics:


        The course of the friction coefficient, specific abrasive wear and temperature were measured on the laboratory testing bench under the following conditions:

        • Specific pressure: p = 0.5 – 3.0 MPa
        • Sliding speed: v = 10 – 30 m.s-1
        • Friction surface: special cast iron CNMCH
